Tape Drive Technology Comparison Sony AIT · Exabyte Mammoth · Quantum DLT By Roger Pozak Boulder, CO (303) 786-7970 [email protected] Updated April 1999 1 Introduction Tape drives have become the preferred device for backing up hard disk data files, storing data and protecting against data loss. This white paper examines three leading mid-range tape drives technologies available today: Sony AIT, Exabyte Mammoth and Quantum DLT. These three technologies employ distinctly different recording formats and exhibit different performance characteristics. Therefore, choosing among and investing in one of these technologies calls for a complete understanding of their respective strengths and weaknesses. Evolution of Three Midrange Tape Drive Technologies Exabyte introduced the 8mm helical scan tape drive in 1985. The 8mm drive mechanical sub-assembly was designed and manufactured by Sony while Exabyte supplied the electronics, firmware, cosmetics and marketing expertise. Today, Exabyte’s Mammoth drive is designed and manufactured entirely by Exabyte. Sony, long a leading innovator in tape technology, produces the AIT (Advance Intelligent Tape) drives. The AIT drive is designed and manufactured entirely by Sony. Although the 8mm helical scan recording method is used, the AIT recording format is new and incompatible with 8mm drives from Exabyte. Quantum Corporation is the manufacturer of DLT (Digital Linear Tape) drives. Quantum purchased the DLT technology from Digital Equipment Corporation in 1994 and has successfully developed and marketed several generations of DLT drive technology including the current DLT- 7000 product. Helical Scan vs Linear Serpentine Recording Sony AIT and Exabyte Mammoth employ a helical scan recording style in which data tracks are written at an angle with respect to the edge of the tape. -
Secure Data Storage – White Paper Storage Technologies 2008
1 Secure Data Storage – White Paper Storage Technologies 2008 Secure Data Storage - An overview of storage technology - Long time archiving from extensive data supplies requires more then only big storage capacity to be economical. Different requirements need different solutions! A technology comparison repays. Author: Dr. Klaus Engelhardt Dr. K. Engelhardt 2 Secure Data Storage – White Paper Storage Technologies 2008 Secure Data Storage - An overview of storage technology - Author: Dr. Klaus Engelhardt Audit-compliant storage of large amounts of data is a key task in the modern business world. It is a mistake to see this task merely as a matter of storage technology. Instead, companies must take account of essential strategic and economic parameters as well as legal regulations. Often one single technology alone is not sufficient to cover all needs. Thus storage management is seldom a question of one solution verses another, but a combination of solutions to achieve the best possible result. This can frequently be seen in the overly narrow emphasis in many projects on hard disk-based solutions, an approach that is heavily promoted in advertising, and one that imprudently neglects the considerable application benefits of optical storage media (as well as those of tape-based solutions). This overly simplistic perspective has caused many professional users, particularly in the field of long-term archiving, to encounter unnecessary technical difficulties and economic consequences. Even a simple energy efficiency analysis would provide many users with helpful insights. Within the ongoing energy debate there is a simple truth: it is one thing to talk about ‘green IT’, but finding and implementing a solution is a completely different matter. -
Media Draft Appendix
Media Draft Appendix October, 2001 P C Hariharan Media Historical evidence for written records dates from about the middle of the third millennium BC. The writing is on media1 like a rock face, cave wall, clay tablets, papyrus scrolls and metallic discs. Writing, which was at first logographic, went through various stages such as ideography, polyphonic syllabary, monophonic syllabary and the very condensed alphabetic systems used by the major European languages today. The choice of the medium on which the writing was done has played a significant part in the development of writing. Thus, the Egyptians used hieroglyphic symbols for monumental and epigraphic writing, but began to adopt the slightly different hieratic form of it on papyri where it coexisted with hieroglyphics. Later, demotic was derived from hieratic for more popular uses. In writing systems based on the Greek and Roman alphabet, monumental writing made minimal use of uncials and there was often no space between words; a soft surface, and a stylus one does not have to hammer on, are conducive to cursive writing. Early scribes did not have a wide choice of media or writing instruments. Charcoal, pigments derived from mineral ores, awls and chisels have all been used on hard media. Cuneiform writing on clay tablets, and Egyptian hieroglyphic and hieratic writing on papyrus scrolls, permitted the use of a stylus made from reeds. These could be shaped and kept in writing trim by the scribe, and the knowledge and skill needed for their use was a cherished skill often as valuable as the knowledge of writing itself. -

3 Secondary Storage.PDF
CAPE COMPUTER SCIENCE SECONDARY STORAGE Secondary storage is needed 1. because there is a limit on the size of primary memory (due to cost) and 2. because RAM is volatile and so data needed for future use must be stored somewhere else so that it can be retrieved when necessary. Secondary storage is also used for backup and archives. When we consider secondary storage devices we must bear in mind the following characteristics of each device : Capacity Access speed Access method and portability Floppy Disk This is a 3.5 inch magnetic disk of flexible material which until recently was a standard feature on most microcomputers. Typically it stores 1.44 MB of data. It’s a thin plastic circle coated with a magnetic material and encased in a rigid plastic to protect it. A metal sliding access shuttle opens when the disk is in the machine allowing the read/write head access to the disk. Data can be written to and erased from a floppy disk. A write protect tab can be used to prevent accidental overwriting of data. Before data can be written to a disk, it must be formatted. This prepares the disk for use by creating a magnetic map on the disks surface. This map consists of tracks and sectors. Formatting also prepares the file allocation table (FAT). The address of a file on a floppy disk is comprised of the track number and the sector number. Floppy disks are direct access devices but they are slow compared to hard disks. The floppies great advantage has been its use as a device to help transport small files between machines. -

History of the Early Days of Ampex Corporation
PAPER History of The Early Days of Ampex Corporation As recalled by JOHN LESLIE and ROSS SNYDER Alexander M. Poniatoff founded Ampex in 1944, primarily to manufacture small motors and generators for military applications. When WWII ended, the military contracts dropped off, and Alex had to search for a new line of business to continue his company’s existence. He and his small group of engineers heard a demonstration of a Magnetophon, a German magnetic tape recorder used by Hitler during WWII. The demonstration quickly convinced Alex to redirect his company and soon it was designing and manufacturing professional-quality magnetic tape recorders. Bing Crosby was a great help in Ampex’s early years. The company grew quickly and, within a short time, dominated the magnetic tape recorder market in radio, television, the record industry, and industrial and military markets for instrumentation recorders . Alex was born in Russia in 1892. His father was well-to- 0 INTRODUCTION do, and sent Alex to Germany for an education in engineering. After college, he returned to Russia only to see his country It has been amazing how many people today are asking become engaged in a civil war. Alex escaped to China, where questions about Ampex and the Company’s contribution to the he went to work for the Shanghai Power Company. He music recording industry, the radio and television broadcast immigrated to the United States in 1927 where he worked for industry and the stereophonic home entertainment field. There General Electric, Pacific Gas & Electric, and the Dalmo Victor is no question that Ampex was a major factor in each of these Corporation in San Carlos, California. -
